This part of IEC 60060 is applicable to:
– dielectric tests with direct voltage;
– dielectric tests with alternating voltage;
– dielectric tests with impulse voltage;
– dielectric tests with combinations of the above.
This part is applicable to tests on equipment having its highest voltage for equipment Um above 1 kV.
NOTE 1 Alternative test procedures may be required to obtain reproducible and significant results. The choice of a suitable test procedure should be made by the relevant Technical Committee.
NOTE 2 For voltages Um above 800 kV meeting some specified procedures, tolerances and uncertainties may not be achievable.
